UNULED STATES EDWARD .L COLEMAN, oF BARRINGToN, RHODE IsLAND.

T all wtom it may concern.:

Be it known that I, EDWARD J. F. CoLF- MAN, a citizen of the UnitedStates of America.,

. and a residentl of Barrington, in the county in Pulley-Blocks,

' mounted on said tie.

space between the rope,

. In view of Bristol and State of Rhode Island, have invented certainnew and useful Improvements of'which the following is a specification.

My invention relates to improvements in pnlleyblocks; and it consists.of an independent link-becket member of peculiar construction adaptedto bebent around the lower teor stud of the block-shello'rframe, wherebya plain or common type ol' block may be readily conve`rted into abecket-blocl,'all as hereinafter set forth and claimed.

' Becket-blochs as usually constructed have' the shell por! ion somewhnt elongatcdbetween the sheavo and the bottom stud or tie whichunites the two sides of the shell together, o.'

metal thimble or grooved fegrule being,- loosely The object of s-ncli isto provide ample served around the thimble, and the sheav'e member, sothat the latter may'turn freely. It, is obvious that such formerbecket-blocks are somewhat heavier, larger, and more expensive thanplain blocks, assuming, of course, that the sheaves arel of the samesize in both cases.

of this fnct itis usual for the blockmnnufaoturer to employ for thebecket-block adirerent and heavier shell than the one used for a plainblock.

By Ineens of my improvement a plain block elongation of the shell maybe"readil v converted inten. becketblock without additionnl cost orpractically without increasing the cost, the becket meinber itself beingconipnratively,inexpensive. 'lhe becket may be attached to the shell' bythe manufacturer of the block, or it may be d one by the purchaser,since the labor in volvcd is simply. to vplace the member inl p'ositionaround thel lower tio or stud of the shell and bend its two end portionstogether, thus at the same time completing the link and forming thebecket-eye to receive the rope.

In the accompanying drawings, Figure 1 is a frontside Aelevation of aplain pulleyblock provided with my improvodlink becket.

Fig. 2 is n corresponding edge vi'ew ofthe V same, the becketmember inboth views being'represented sectiounlly. Fig. 3 is 'a' side view, inpartialsection, of the becket niember or casting before 'being attachedto the block; and Fig. 4 is a Vplan view of the Same'.

In thedrnwings, A indicates a pnlley-block providedwith'my `improvedlink becket B.

The shell or freine a. of the block is or maybe made substantiallyascommon and provided cast metal andv consists of two parte united at topand. bottonib v inwardlyffacing-ties a' a?, respectively, rivets r,therethrpngh, servingto rigidly secure the shell together. The becketmember B may be made of enst metal-as, plier-bronze, scr-or struck upfroinsteel and then galvanized; Iprel'er the former, however. In suchense `the normal shape of the casting is substantially as represented inFig. 3, wherein 4the end portions b are provided with elongated holes eroyes e, the sides passing centrally' for example, phoswith thefreely-turning grooved sbeave or pulley d. As drawn, the shell is madeof thereof being,r beveled and woll ron-nded,tliere v by not onlyadapting the pattern to be more readily drawn from the mold, but alsoforlning when properly bent e. smooth nonnn`gu in r surface fol-the ropeto pass through. The dotted lines in said Fig. 3 show the relation ofthe end porti-ons when completely bentand shaped. 'lhe width of thebecket at the center portion b' may be increased, the thickness beingproportionately decreased, thereby ndnpting the castle to be morereadily bent around the post. ,'l he thickness of the ond portions b ofthebeclcet considerably exceeds l thnt of the center. This is done toincrease the distance through the eye, so es to forma. more serviceablesont forl the rope when secured therein.

In attaching the becket the .casting is Afirst placed in position, sny,as show-n by dotted lines in Fig. i, followed b'y'bending the two endportions b downwardly until they are brought into close engagement witheach other, nt the same time portion b' Inround the tie or post a, thebecket when thus mounted in place being supported by and adapted toswing freely on the said tie. Obviously the becket may be rcadilydetnched from the block-shell, if desired.

pressing the center n win be einen that nl@ axis tf the noieV Vzo E' l Y860m or eye e is ut right angles to that of the snpporting-tie a, thebecketfbl'ock thereby haw ing the" pulley-rope a'nd the bekellrope in a.plane common to both. 5 I would add that after the casting hasheeninserted and bent to form the becket the ends b thereof may be expanded;if deeiredghy means of a suitable mandrel forced into the opening e,thereby enlarging the eye and in- Ivclaim as my invention- In apulley-block, the combination of the two-perl; frame a, provdedatche'bottoi wth a connecting transverse tie or stmd'a, Mivet I 'r passingthrough said tie and securing the frame together, and the link becket Bbent creasing the width of Lheends., (Se'Fig'. 21)' looeelygaronnd thetie, the two end portion of Le becket, which are eousderbly thicker.than ehe center portion, being pressed su ugly together below the tieand provided'ivth' a tfesveisely-armnged eye e to receive a rope,

the axis of the said eye being at right. angles i te' that' of the-tiea'-', whereby the rope, becket and pulley are adapted to move in acommon plane, snhetan Lially as described.
